 Flash memories supported:

 The real flash device names are listed in the Device column. The names of
 compatible/similar devices are listed in the "aliases" column.
 Compatible/similar devices are e.g. combo devices using that particular
 flash device.

 The size column denotes the full device memory size in megabits (Mb). For
 dual and multi-bank devices, two or more numbers indicate the sizes of the
 respective banks, starting from the lowest address.
